Answer:

Part A. For x, we’ll use 1, 2, 3, 4, and 5. Now, we have to plug in the x-values to get f(x) (or y). I’ll do the first two w/ explanations then just give the answers. when x= 1, f(1)= 2/3•1-1. solve accordingly, you get -0.3. Next, when x= 2, f(2)= 2/3•2-1. Solve and you get f(2)= 0.3. when completing and solving for the other 3 x-values, use the same process and plug into the chart with corresponding numbers. A calculator may be helpful.

Part B. Just graph, use the x-values for x and the y-values for y. if u don’t know how to graph u may want to look back on some of your lessons if available.

Thanks.

(b) Find the angle between u and v to the nearest degree.
yulyashka [42]

<u>Question 1 (b)</u>

<u />u \cdot v=11\\\\|u|=\sqrt{3^{2}+(-1)^{2}}=\sqrt{10}\\\\|v|=\sqrt{4^{2}+1^{2}}=\sqrt{17}

So,

\cos \theta=\frac{11}{\sqrt{10}\sqrt{17}}\\\\\theta=\cos^{-1} \left(\frac{11}{\sqrt{10}\sqrt{17}} \right) \approx \boxed{32^{\circ}}

<u>Question 2 (b)</u>

<u />u \cdot v=22\\\\|u|=\sqrt{5^{2}+2^{2}}=\sqrt{29}\\\\|v|=\sqrt{4^{2}+1^{2}}=\sqrt{17}

So,

\cos \theta=\frac{22}{\sqrt{29}\sqrt{17}}\\\\\theta=\cos^{-1} \left(\frac{22}{\sqrt{29}\sqrt{17}} \right) \approx \boxed{8^{\circ}}

Answer:

  shaded/square = (50π cm²)/(400 cm²) = π/8

Step-by-step explanation:

The quarter circle has area ...

  A = (1/4)(πr²) = π/4(20 cm)² = 100π cm²

The half-circle has area ...

  A = (1/2)(πr²) = π/2(10 cm)² = 50π cm²

Then the area of the shaded portion is ...

  shaded = 100π cm² -50π cm² = 50π cm²

__

The area of the square is ...

  A = s² = (20 cm)² = 400 cm²

Then the ratio of interest is ...

  shaded/square = (50π cm²)/(400 cm²) = π/8
